Fig. 2 is a sectional view `of the operating mechanism taken on the line 2-2 -of Figure 1. 1

erence indicate corresponding partsfin each figure.

The numeral 1 indicates generally a plate having apertures 2 adjacent one end for the reception of screws or other fastening means, whereby .the device is secured in a suitable position on a motor car. The outer end of the plate is substantiallyA circular in form as at 3 and is fitted with a cover 4 'secured by any suitable means. An offset plate 5, see Figure 2, is supported from the plate 1 and in parallel relation thereto, to permit of an indicating arm generally indicated by the numeral 6, being swingingly mounted therebetween.

The indicating arm 6 comprises a boxlilre base portion 7 having side plates 8 and pins 9 and 1() forming trunnions upon which the arm swings. Secured to the base portion 't' is an elongated casing 11 preferably formed in the shape of a dart and having front and rear openings 12 covered with a suitable translucent material preferably red in col'- our at the 'rear and green at the front. Carried between the plates 8 is a socket 13 and an electric bulb 14. In the device as shown the socket 13 is grounded to the base portion 7 and through the plate 1 to the metal por- In the drawings like characters of ref-v rivnronron 4,1927.; serial Nggeeinai;

spring being so applied as to draw the indicator arm 6 downward and to hold it against vibration when the vehicle to which it isfit` .Y

ted is: in motion.

The plate 1 is provided with an arcuate v slot 21 concentric with the pin 10 through which a pinl 22 extends and is pivotally secured tothe base portion 7 as at 23. The outer end ofthe pin 22 is slotted as at 24 and isV adapted to receive a pullwirej25 having a button 26 atk its inner end, which wire is held against lifting from the slot 24 by a split pin 27 extending thereacross. Suitably supported from the base plate 1 is a iexible tube 28 which forms a housing for the pull wire 25 and is attached at its outer end to a suitable controlling device adjacent the drivers seat, whereby 'as the wire 25 is pulled, the indicating arm 6 is swung upwardly and outwardlyrrto indicate the contemplated action of the driver. Secured to the plate 1 is a block of insulating material 29 upon which is mounted a spring contact arm 3() extending over the contact button 16 and adapted to contact therewith. The contact arm is connected within the lighting circuit by a conductor 31. As a means of breaking lthe Contact between the Contact varm 30 and the button 16 an insulating stud 32, having a dome shaped upper extremity 33, is provided uponthe flange 17 of the pin 10 in such a position as to slide under the arm 30 to raise it from cont-act with the button 16V as theindicating arm 6 is lowered outof indicating position, thus breaking the electric lighting circuit.

It will be obvious that as the control device is operated to pull the wire 25 and swing the indicating arm 6 outwardly and upwardly, that the stud 32 will be withdrawn from under the contact arm 30, thus closing the electrical circuit and illuminating the bulb 14, thereby rendering the device con-V spicuous to other users of theroad. What We claim as our invention:

A direction indicator comprising a sup--V porting plate,`a signal arm secured to the plate by a pivot about which the arm is movable to and from indicating positions, a projecting pin having one terminal rotatably secured to said arm and the other` terminal protruding through an arcuate slot -formed in said supporting plate, said slot being concentric to said pivot, and means secured to the protruding terminal of saidv pin t-o move the pin longitudinally of said slot in order to eii'ect swinging movement of said arm to a direction signalling position.
